System Configuration Example
The following diagram shows the operating procedure using a system config-
uration example. The system configuration shown here uses Thin Cables.
Power is supplied to each node in the above diagram using the following
devices.
Internal power: S82K-05024 (100 V AC, 50 W)
I/O power:
S82K-05024 (100 V AC, 50 W)

Preparations
Selecting Units
Select the following Units as shown in
2-1-2 System Configuration Example
.
Master Unit:
C200HW-DRM21-V1
Slave Units:
DRT1-ID16
DRT1-OD16
DRT1-TS04T
C200HW-DRT21
DRT1-232C2
There is a complete line of OMRON Master Units and Slave Units available
that are compatible with DeviceNet. Select Units that suit the needs of the
system. For further details on types of Units, refer to
1-1-2 Slaves
.
Wiring
Either Thick Cables or Thin Cables can be used to wire a DeviceNet Network.
Flexible branching of cables is possible by using either T-branch Taps or
multi-drop connections. Restrictions on the maximum network length and total
branch line length depends on the baud rate and type of cable used. For
details, refer to the
DeviceNet Operation Manual (W267)
.
In
2-1-2 System Configuration Example
, Thin Cables are used with T-branch
Taps for connecting Slave Units to the trunk line.
Communications Power
Supply
Each node (Master or Slave) must be supplied with a 24-V DC power supply
for proper DeviceNet communications. The communications power, however,
can be supplied by communications cables and does not require separate wir-
ing.
For systems that have a short maximum network length, power can be sup-
plied to all nodes by using one communications power supply. Various condi-
tions, constraints, and measures affect how the communications power is
